Patrons at Lumen Thursday expected to see R&B singer Ciara, who was making a schedueled appearance on behalf of Hennessy V.S.

The Derrick Rose sighting on the opposite side of the club?

That was a bonus. Still, it wasn't completely unexpected. Like many other Chicago athletes, the Bulls star has been to known to hang out at Lumen. The Bears' Kelvin Hayden was also there that night.

Prior to the appearance, Ciara performed a private WGCI show at the House of Blues. Singer/actress Jennifer Hudson was on hand for the show and posed for photos with Ciara, which they both posted on Twitter.

Rapper Ludacris -- who you might remember was featured on Ciara's song "Ride" -- had dinner Sept. 20 at Gibson's Steakhouse in the Gold Coast.
